UFS installs solar plants on all campuses, bolstering renewable energy amid continuing power cuts

Bloemfontein Campus Solar Farm — The solar plant on the UFS’s Bloemfontein Campus, part of the university’s commitment to combatting loadshedding and embracing sustainable energy.

The University of the Free State (UFS) has installed solar plants across its three campuses.

The university says this is in response to the call for urgent solutions to loadshedding and the promotion of environmentally sustainable, cleaner, and renewable energy solutions.

Nicolaas Esterhuysen, Director of Engineering Services at UFS University Estates, said,

“The PV (photovoltaic) systems are grid-tied without storage to ensure maximum benefits and faster payback periods.”

Esterhuysen said the UFS has saved up to R32,5 million since the first solar plant was commissioned in 2017 to help the UFS reduce the impact of loadshedding and its carbon footprint and energy costs. “This will substantially increase this year with the commissioning of two large new ground-mounted solar plants on the Bloemfontein Campus,” he said.

“The microgrid installation on Qwaqwa Campus is one of the biggest solar diesel hybrid systems installed in South Africa. It allows us to keep the campus running despite excessive power interruptions.”

The UFS is currently embarking on research as part of the Grid-related Research Group (GRRP) under the Interdisciplinary Centre for Digital Futures (ICDF) to also help staff and students with understanding renewable energy and sustainability.

Esterhuysen said the plants are further evidence of the UFS’s commitment to renewable and energy saving solutions. “It is our flagship project, but our focus is also on energy saving initiatives – to ensure we are becoming more energy efficient and eliminate energy wastage. We have plans for expansion on all campuses. Some of the highlights are an off-grid solution for the new student centre at Qwaqwa Campus and to make South Campus a self-sustaining campus.”

The installed grid-tied system solar plants are operating without batteries on all three campuses, giving the university an optimal configuration between capital cost and payback period.

The energy generated at the solar plants:

Bloemfontein Campus – 3688 kWp

Qwaqwa Campus – 918 kWp

South Campus – 759 kWp

Paradys – 125 kWp

UFS Ground Studies Laboratory receives accreditation to international standard

The Institute for Groundwater Studies (IGS) Laboratory at the University of the Free State is on equal footing with international testing labs. With its accreditation in March 2016 by SANAS (South African National Accreditation System), the IGS Laboratory now officially meets global standards.

Quality of water

The IGS Laboratory mainly analyses the quality of water samples. When it was originally established in 1989, the lab’s central function was to conduct testing for researchers at the institute itself. “After the public and water boards realised their need to analyse water samples, the IGS Laboratory expanded to deliver a service to these clients,” says Lore-Mari Deysel, Deputy-Director of the institute.

Since suppliers and regulatory authorities will not accept test or calibration results from a lab that is not accredited, the IGS initiated the accreditation process.

Accreditation to international standard

In order to be deemed technically competent and able to receive accreditation, labs must meet the ISO/IEC 17025 standard. ISO/IEC 17025 was first issued in 1999 by the ISO (International Organization for Standardization) and the IEC (International Electrotechnical Commission).According to Deysel, this is the single most important standard for calibration and testing laboratories around the world.

“Laboratories that are accredited to this international standard have demonstrated that they are technically competent and able to produce precise and accurate test and/or calibration data. Furthermore, it demonstrates that the university has the capacity to supply valuable and reliable services alongside the academy,” Deysel says.
